Which statement about Zika virus infection is true?

Zika virus infection is often asymptomatic, so asymptomatic infections are common. When symptoms do occur, they’re usually mild and brief, and not everyone experiences fever and rash. Transmission isn’t limited to mosquitoes; it can occur through sexual contact, from mother to fetus, and via blood transfusion, so the idea that there is no person-to-person transmission isn’t accurate. Because many infections don’t cause noticeable illness, public health emphasis is on mosquito control and preventing sexual transmission, particularly to protect pregnancies from potential birth defects.
